For infrared absorption measurements, the following five isotopic polyglycines have been prepared: ordinary polyglycine (—NHCH 2 CO—) n , N ‐deuterated polyglycine (—NDCH 2 CO—) n , C ‐deuterated polyglycine (—NHCD 2 CO—) n , completely deuterated polyglycine (—NDCD 2 CO—) n , and N 15 ‐substituted polyglycine (— 15 NHCH 2 CO—) n . Infrared spectra have been observed both in the I and II forms of each of these five isotopic polyglycines in the spectral region of 4000–300 cm. −1 . On the basis of the comparison of these spectra with each other, a nearly complete set of assignments of the observed bands of polyglycines has been given.
